The Tiyas Air Base, also known as the T-4 Air base, is a Syrian Arab Air Force (SyAAF) base located in the Homs Governorate, north of Tiyas, and west of the ancient city of Palmyra, Syria.
Tiyas is the largest airbase in Syria.[2]
During the 1970s and 1980s, the Soviet Union was given access to the Tiyas Air Base for the periodic deployment of naval aircraft.
The airbase was used by the Syrian Arab Air Force and Iran's Quds Force for military operations against ISIL and opposition forces during the Syrian Civil War.[3]
See main article: article and Palmyra offensive (December 2016). In December 2016, the Islamic State of Iraq and the Levant (ISIL) attacked the airbase a day after overrunning pro-government forces in nearby Palmyra. ISIL claimed to have destroyed four Syrian military aircraft during their attack on the airbase.
The Israeli Air Force launched an attack on the airbase on 10 February 2018, destroying the main observation tower, according to the Syrian Observatory for Human Rights.[4]
The base was struck again on 9 April 2018 by multiple missiles, it was not immediately clear who was behind the attack however U.S officials denied launching any air attack on Syria.[5]
It was reported that the April 2018 attack on the base destroyed a hangar used to shelter drones and an Iranian supplied anti-aircraft Tor missile system, before it could be set up and become fully operational.[6] [7] [8]
T-4 air base has been used by Iran-backed Shia militias to launch drone strikes against U.S. bases in northern Syria during summer 2021.[9]
Israeli warplanes attacked the airbase with missiles again on 8 October 2021 around 9:30 pm. Six Syrian soldiers were injured according to Syrian media. Israel claims that the airbase is still used by Iranian forces.[10]
